Summary
The distribution of the various elements present in films obtained by a modified alloy zincate immersion treatment on aluminium was studied using electron probe microanalysis, energy dispersive analysis on a scanning electron microscope and Auger electron spectroscopy. As expected, zinc was the main component of the film; however appreciable concentrations of copper were found towards the film/substrate interface. Another unexpected result was the variation in spatial distribution of some elements.
